Hello,  
i’ve encountered a somewhat weird problem. In my code i had to check if one specific argument was provided by the user, so i did something in these lines :

```auto
import openturns
openturns.Point([1,1,1]) == None

```

this resulted in my kernel crashing and being unable to restart.

Once i’ve determined the root cause of the problem i was able to rewrite my code and to work around the problem. I just thought it could be useful to correct it in some future release

regards

sanaa

good catch, I’ll fix it  
instead of “if x == None” we write these as “if x is None”, which works in the current version
